Jack Bidderhous played this trophy in some jerkwater bar, called The Groaning Crow, back in the early 50's. Jack had one mission in life, and one mission only. He wanted to produce an electric guitar so when the Dm9-xx0968 chord was strummed and amplified through his K amp, at a volume of 8.1 on the dial, a certain vibration in tone would induce a specific "pleasuring" of the female clientele of The Groaning Crow. He tweaked, twisted, and tortured his guitar with add-on harmonic felbers and some very dangerous sonic mosas that he renamed "Thresholds." He then proceeded to work the Dm9-xx0968 chord into every song he wrote. I don't know if it worked because I don't know how to fret the Dm9-xx0968 chord.
